Key Verses

1. 2:219Al-Baqarah
   ۞يَسۡـَٔلُونَكَ عَنِ ٱلۡخَمۡرِ وَٱلۡمَيۡسِرِۖ قُلۡ فِيهِمَآ إِثۡمٞ كَبِيرٞ وَمَنَٰفِعُ لِلنَّاسِ وَإِثۡمُهُمَآ أَكۡبَرُ مِن نَّفۡعِهِمَاۗ وَيَسۡـَٔلُونَكَ مَاذَا يُنفِقُونَۖ قُلِ ٱلۡعَفۡوَۗ كَذَٰلِكَ يُبَيِّنُ ٱللَّهُ لَكُمُ ٱلۡأٓيَٰتِ لَعَلَّكُمۡ تَتَفَكَّرُونَ
   They question thee about strong drink and games of chance. Say: In both is great sin, and (some) utility for men; but the sin of them is greater than their usefulness. And they ask thee what they ought to spend. Say: that which is superfluous. Thus Allah maketh plain to you (His) revelations, that haply ye may reflect.
   In context

   O Prophet! Your Companions ask you about wine (which refers to anything that impairs the mind or intoxicates it), with respect to the legal aspects of drinking, selling and purchasing it. They also ask you about gambling (which refers to wealth taken in a competition between two people in which both contribute to the winning total).

2. 2:280Al-Baqarah
   وَإِن كَانَ ذُو عُسۡرَةٖ فَنَظِرَةٌ إِلَىٰ مَيۡسَرَةٖۚ وَأَن تَصَدَّقُواْ خَيۡرٞ لَّكُمۡ إِن كُنتُمۡ تَعۡلَمُونَ
   And if the debtor is in straitened circumstances, then (let there be) postponement to (the time of) ease; and that ye remit the debt as almsgiving would be better for you if ye did but know.
   In context

   If the person from whom you demand your debt is in hard times and is unable to repay the debt, then refrain from asking until he is able to obtain money and then pay the debt. And to give charity to him by not demanding the debt or giving up a part of it is better for you, if you knew its worth in the sight of Allah.

3. 5:90Al-Maidah
   يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓاْ إِنَّمَا ٱلۡخَمۡرُ وَٱلۡمَيۡسِرُ وَٱلۡأَنصَابُ وَٱلۡأَزۡلَٰمُ رِجۡسٞ مِّنۡ عَمَلِ ٱلشَّيۡطَٰنِ فَٱجۡتَنِبُوهُ لَعَلَّكُمۡ تُفۡلِحُونَ
   O ye who believe! Strong drink and games of chance and idols and divining arrows are only an infamy of Satan's handiwork. Leave it aside in order that ye may succeed.
   In context

   O you who have faith in Allah and follow His Messenger, intoxicants that affect the mind, gambling with a consideration from both sides, stone alters on which the idolaters offer sacrifices or which they erect for worship, and arrows by which they used to draw lots – these are all acts of sin that Satan has made attractive.

4. 5:91Al-MaidahWarning
   إِنَّمَا يُرِيدُ ٱلشَّيۡطَٰنُ أَن يُوقِعَ بَيۡنَكُمُ ٱلۡعَدَٰوَةَ وَٱلۡبَغۡضَآءَ فِي ٱلۡخَمۡرِ وَٱلۡمَيۡسِرِ وَيَصُدَّكُمۡ عَن ذِكۡرِ ٱللَّهِ وَعَنِ ٱلصَّلَوٰةِۖ فَهَلۡ أَنتُم مُّنتَهُونَ
   Satan seeketh only to cast among you enmity and hatred by means of strong drink and games of chance, and to turn you from remembrance of Allah and from (His) worship. Will ye then have done?
   In context

   By making alcohol and gambling seem attractive, Satan’s only intention is to create hatred between hearts and to turn them away from Allah’s remembrance and from the prayer. Will you, O believers, leave these evil acts? Without doubt, leaving these acts is the right thing to do, so avoid them.
